Epoxy resin coating application of crosslinking agent,Epoxy resin for laminated composite resin for special purpose, to good bonding effect between fiber bundles, particularly suitable for making high performance fiber reinforced material such as carbon fiber, aramid fiber composite materials.
Epoxy resin mixture is a kind of transparent, light amber, low viscosity liquid. Is the foundation of all epoxy products, with specific after crosslinking agent can be used for wood, glass fiber, and most of the bonding metal, also can do laminating resin.
At room temperature, using a dedicated pump with a specific crosslinking agent according to the scale of production, but in a broad range of temperatures high bonding strength of solid, and it has excellent resistance to moisture. This highly moisture-resistant features, can be applied to various kinds of materials, is the ideal choice for waterproof, resistance to chemical corrosion project, its strong physical properties can also be used for structural adhesive. This is specifically for saturated and gluing wood fiber, glass fiber, reinforcing fiber, foam composite material and various metals.
When mixed with specific packing, epoxy resin can make up for gaps and fill the gap, when the glue can be used sand paper burnish and form a certain shape. Roller application has a good film characteristics, do not form fisheye. The layers of epoxy resin coating, can create a good performance for paints and varnishes moistureproof layer and the basis of the sturdy.
Epoxy is a volatile solvent, not shrink after crosslinking. It has a relatively high flash point, there is no strong smell of solvents, compared with polyester and vinyl ester resin, better security. At 72 ℉ (22 ℃), the viscosity is about 1000 cp. According to the different use, select the most appropriate crosslinking agent.
Ratio (weight) for 5 to 1 301 standard micro metering pump, suitable for use 205 standard crosslinking agent and 206 type slow crosslinking agent system. Ratio of 3:1 (weight) 301 standard micro metering pump, suitable for use 207 coating special crosslinking agent and 209 type super slow crosslinking agent system.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Raw material ：
TDA industrial, Sichuan production
Ethylene (Et) polymer grade, Shanghai production
TEA industrial imports
A reagent grade additives
Crosslinking speed varies according to the operating temperature. In the warm temperature, epoxy resin crosslinking speed faster, in cool temperatures, applied on the surface of thicker and thinner, epoxy crosslinking is relatively slow.
Some special epoxy resin products designed for penetration and reinforcing the rotten wood. These products are generally after solvent dilution of epoxy resin, permeability is used to do a good wood.
But solvent the assembly and the strength of the epoxy resin and moisture characteristics. WEST SYSTEM epoxy resin can be solvent dilution in order to gain greater permeability, but also affect its strength and moisture resistance.
Acetone and paint thinner, also can be used to dilute WEST epoxy resin SYSTEM, on the premise of guarantee the same effect increase the permeability of epoxy resin. If you choose to dilution of epoxy resin, please remember according to add the proportion of different solvent, the strength of the epoxy resin, especially the compressive strength and moisture resistance will decrease accordingly.
In the case of no loss of strength or moisture resistance, in order to obtain good invasive, we recommend that before using epoxy resin, with a heat gun or heat lamp for moderate heating repair area. When exposed to heat wood, epoxy resin can become thin, through the hole and porosity, and even into the wood in the cooling of the air hole.
Although will shorten the service life of the epoxy resin, but slow crosslinking agent before long service life and crosslinking, its penetration than crosslinking agent. When epoxy resin crosslinking, it will remain as moistureproof layer the intensity and effect of the original, than the effect brought by the solvent is added into the epoxy resin is better.
